Flashcard Practice AWS Certified Machine Learning Engineer - Associate Multiple Choice

A company wants to recommend products by traversing relationships among users, viewed items, purchases, categories, and similar users. The current DynamoDB design requires many queries and client-side joins. What is the most defensible change?

Choose the Best Answer

Move the data to ElastiCache and scan every key for related users during each request Store each relationship as a separate container image tag in ECR for versioned recommendation lookup Add a random suffix to each DynamoDB partition key so traversals are spread across more partitions Model the connected entities and relationships in Neptune and query the recommendation paths with an appropriate graph query language
